writePWMVoltage

Generate PWM signal with specified voltage on digital pin

Add-On Required: This feature requires the MATLAB Support Package for Arduino Hardware add-on.

Syntax

writePWMVoltage(a, pin, voltage)

Description

writePWMVoltage(a, pin, voltage) writes the specified voltage value to the PWM pin on the Arduino^® hardware.

Examples

Specify the Voltage of Digital Pin

Specify digital pin 5 on Arduino hardware to have 3 volts.

a = arduino();
writePWMVoltage(a,'D5',3);

Input Arguments

a — Arduino hardware connection

object

Arduino hardware connection created using arduino, specified as an object.

pin — Digital pin number

character vector

Digital pin number on the physical hardware, specified as a character vector.

voltage — Voltage of the digital pin

numeric

Voltage of digital pin’s PWM specified as number between 0 and 5 volts. Check your hardware data sheet for accepted voltage ranges. For more information, see Supported Boards.

More About

Code Generation Using MATLAB Function Block

• Use writePWMVoltage in a MATLAB^® Function block with the Simulink^® Support Package for Arduino Hardware to generate code that can be deployed on Arduino Hardware.

• Configure the Arduino peripherals to the appropriate mode using configurePin before using writePWMVoltage in the MATLAB Function block.
